+DigiPres Toolbox
+----------------
+
+A Docker image designed to make it easy to experiment with tools for Digital Preservation.  Designed to be used via the [DigiPres Sandbox](https://github.com/digipres/sandbox) and the [DigiPres Workbench](https://github.com/digipres/workbench).
+
+## Supported Tools
+
+### Pre-installed
+
+Only light-weight tools are pre-installed, so the Docker image size (and hence Sandbox launch times) can be kept low.
+
+ - [Siegfried](https://www.itforarchivists.com/siegfried) (using the 'deluxe' format signatures which includes mutliple sources).
+ - [File](https://www.darwinsys.com/file/)
+ - [TrID](http://mark0.net/soft-trid-e.html)
+ - [MediaInfo](https://github.com/MediaArea/MediaInfo)
+ - [CLOC](https://github.com/AlDanial/cloc)
+
+### Verified Installable
+
+These aren't installed by default, but the [Sandbox](https://github.com/digipres/sandbox) shows how to install them.
+
+ - [Apache Tika](https://tika.apache.org/)
+ - [DROID](http://digital-preservation.github.io/droid/)
+ - [Fido](https://github.com/openpreserve/fido)
+ - [ffmpeg](https://ffmpeg.org) including [ffprobe](https://ffmpeg.org/ffprobe.html)
+ - [GitHub Linguist](https://github.com/github/linguist)
